Hi all,

 

Anyone know what species/genus this bivalve steinkern is? It's from Rivière-sur-Tarn, a location in France that yields fossils from the Toarcian stage of the early Jurassic (approx 180 mya). 

 

Best regards,

 

Max

However, I wast just reading a book about fossils and there i saw a picture of a spiriferina sp. . This might be a better determination than digonella sp.

Might be a digonella sp.? I'm not sure at all on this one.

Edit: I think it might be pathollogical.

You're in the wrong field there, friend ;)

This is a bivalve steinkern, and you're suggesting brachiopods...

I still appreciate the help, thanks!

Perhaps a Pholadomya?

Maybe. But I'm not finding any Pholadomya steinkerns pictures to compare with...

No, it's not pathological. Comparative steinkerns are the below ones from Toarcian-Pliensbachian of Aveyron, France.

The odd "spongy" thing on mine is indeed just detritus, and I think it can be taken off with some prepping. Indeed no pathology on this one!

 

if the genus of this one is indeed Pholadomya, then the species will be P. voltzii Link as it's the only Pholadomya of the Toarcian of France. 

 

Thanks everyone!

maybe Palaeonucula   (? P. hammeri, toarcian)

Thanks for the help, that does seem like a good match! :D
